N a signal used to warn railway engine drivers in fog, consisting of a detonator placed on the line 雾中警示信号灯
In this paper, a kind of digital lockin amplifier used in FOG signal detection is designed.
提出了一种用于光纤陀螺信号检测的数字锁相放大器的设计方法。
Fog sets in, call master at once. Began to keep on radar for detecting to the sea all round at an interval of every 20 minutes. Sounding by echo 52 fathoms. Standby Engine. Fog signal started.
雾起，立即召唤船长，开始保持每20分钟用雷达环扫一次海面，回声测深52拓，备车，开启雾号。
But, the FOG precision developed in China is generally lower also the GPS has the congenital flaw which signal can be disturbed.
但目前国内光纤陀螺精度普遍较低而GPS又有信号易受干扰的先天缺陷。
